Which of the following examples best represents an object with balanced forces acting upon it? a
A book sitting on a high shelf
b
A baseball is thrown in the air
c
A boat moving through water
d
A wagon rolling down a steep hill

A. a book sitting on a high shelf.

The book's force is pushing down while the shelf's force is pushing up against the book at an equal force helping it balance. The answer would be B.

Step-by-step explanation:

I hope this answered your question.

(Brainliest would be appreciated.)

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
